Summary
Transverse testicular ectopia, a rare condition where a testis migrates to the opposite groin, was diagnosed during surgery in a young boy. Both testes were successfully repositioned in the scrotum.
Area of Science:
- Pediatric Surgery
- Urology
- Developmental Biology
Background:
- Transverse testicular ectopia (TTE) is an extremely rare congenital anomaly.
- It involves the migration of one testis to the contralateral inguinal canal, often associated with inguinal hernia.
- Accurate preoperative diagnosis of TTE is infrequent, with most cases identified intraoperatively.
Observation:
- A case report details an 11-year-old boy initially operated for left inguinal hernia at 10 months, with the right testis absent.
- During a subsequent surgery for left inguinal hernia at age 10, both testes were found in the left inguinal canal.
- The right testis was fixed in the left hemiscrotum, and the left testis was translocated to the right hemiscrotum via a modified Ombrédanne operation.
Findings:
- Postoperative ultrasonography and voiding cystoureterography revealed no other genitourinary anomalies.
- The etiology of crossed testis ectopia may involve gubernacular rupture and genitofemoral nerve dysfunction.
- While imaging can aid localization, intraoperative diagnosis remains common for TTE.
Implications:
- Surgical management of TTE includes laparoscopic and open procedures, with orchiopexy tailored to testicular position and cord length.
- Atrophic testes may require removal, while fused testes are repositioned into one hemiscrotum.
- This case highlights the importance of intraoperative vigilance for rare anomalies like TTE.
